REGULATOR FOR MOTORS FOR MUSIC-BOXES, 86C- SPEGIFICATION forming part ofLetters Patent No. 442,609, dated December 16, 1890.

Application filed July 19, 1890- Serial No. 359,278. [No model.)

To all whom it may concern:

Be it known that I, LOUIS OAMPIOHE, a resident of Ste. Oroix,Switzerland, have invented an Improved Regulator for Motors for Music-Boxes, &c., of which the following is a specification, reference beinghad to the accompanying drawings, forming part of the same, wherein-Figure 1 represents a plan or top View of my improved regulator, showingit applied in connection with the driving mechanism of a music-box. Fig.2 is an enlarged top view of part of said regulator. Fig. 3 is a sideView, partly in section, of said regulator, the line 0 c, Fig. 1,indicating the plane of section. Fig. 4E is a bottom view of the same;Fig. 5, an end elevation of the same, showing the inner end; Fig. 6, adetail vertical section on the line k 70, Fig. 3. Fig. 7 is a side viewof a modification of my invention, and Fig. 8 an end elevation of thesame.

The object of this invention is to supply a music-box and analogousmechanism with an automatic regulator, which shall serve to equalize thespeed of the thing rotated or moved by spring-power, (in the case of amusic-box the speed of the studded cylinder,) so that when the spring ismost powerful and fully wound it shall not drive said mechanism (orcylinder) faster than when the spring is about unwound. One of thedifficulties with such mechanism and one which has made itself felt mostparticularly in the matter of music-boxes is that the cylinder revolvestoo fast when the spring is fully wound and too slow when the spring isnearly unwound, the proper speed being ordinarily obtained only betweenthe extremes of spring-power just stated. My attachment seeks to opposeto the spring a resisting force proportional to the excess ofspring-power, so that the speed obtained throughout will be equal tothat of the spring when nearly unwound.

My invention consists, mainly, in combining with the arbor of the flycertain spring resistance-pieces, which will be strained by longitudinalor vertical motion of said arbor when the same is exposed to a greaterpower than necessary for the desired speed,thus 0btaining a brake actionupon the fly-arbor which is proportional in force to the springpower andwhich ceases to act as the spring is totally unwound.

The invention also consists in other details of im provernentflhat willbe hereinafter more fully described.

In the accompanying drawings, the letter A represents theinainspring-drum of a suitable music-box, and the letter B indicates themain toothed wheel, which is connected with the mainspring and rotatedthereby.

The letter 0 represents the studded cylinder of a music-box, which isconnected with the inainspring in such a manner as to be revoledthereby; but, as already stated, this invention is not intended to belimited to a music-box, as it is applicable to all mechanism of ananalogous character-that is, Where a mainspring enters into combinationwith a worm to produce a desired motion. The toothed wheel B meshes intoa pinion a, on the arbor of which is a toothed wheel I), which meshesinto a pinion d, on the arbor of which there is a worm-wheel c. Thisworm-wheel engages a worm f on an arbor g, which arbor carries a fly D.

E is a stationary frame, in which the arbors of the toothed wheels at Z)and (l e have their bearings, and in which the arbor g of the fly D islikewise supported; but the arbor g.is longitudinally movable, as shownin Fig. 3, or vertically movable, as shown in Figs. 7 and 8, in itsbearings h and i, that project from and are part of the frame E. Infact, the arbor 9 passes through the bearing iand its end is in contactwith a yielding resistancepiece, which may be a lever F or spring F,which lever at-j is pivoted or attached to the frame E, and which at itslower part is in contact with a spring Z. This spring Z tends to pressthe lower part of the lever F outward and the upper part of the samelever inward, tending, therefore, to crowd the flyarbor g in thedirection of the arrow 1 in Fig. 3that is, inward. The yieldingresistancepiece where the end of the arbor g bears against it may have acrystal or jewel to ease the friction between the end of the arbor andsaid yielding resistance-piece. The arbor 9 also bears a collar m inclose proximity to a spring n, (see Figs. 2, 7, and 8,) which extendsinward from the frame E near the lever F,

and which may take the place of the spring Z, as shown in Figs. 7 and 8.The spring Z, which causes the lever F to be a yielding lever, is shownto be in form of a coiled spring surrounding a sliding bar G and to beconfined between a collar 0 on said bar and the the lower end of thelever F. The bar G may be pushed outward by a hand-lever II, which isprovided with a bevel at p for this purpose, so as to compress thespring Z to a greater or less extent, the hand-lever I-I having itshandle portion 0" passing through a slot of a plate .9, that isstationarily secured to the frame E.

Having now described the mechanism of my invention, I will briefly statehow it op erates. The spring A, being wound, rotates the wheel B, andthis by suitable intermediate gearing (in the illustration by the wheelsat Z) (Z) revolves the worm-wheel e, which in turn revolves thefiy-arbor g. The direction in which the Wheel 6 is thus turned isindicated on said wheel by arrow 2 in Figs. 3 and 7that is to say, theworm f 011 the arher 9 is revolved by the application of pressuretendingto crowd the arbor g toward the lever F. WVhenever this pressureis normal that is to say, not in excess of the desired speedit will haveno noticeable effect upon the longitudinal position of the arbor g; butwhen the power of the spring A is abnormally great the worm-wheel 0 willmove the arbor g lengthwise or vertically and crowd it against thespring F or lever F, thus eX- posing it to the yielding resistance ofsaid lever, and this resistance of the spring F or lever F produced bythe motion of the arbor 9 against it causes a correspondingly greaterfriction on said arbor and a resulting retardation of the movement ofthe fly, which in turn retards the speed of the wheel B. Right here Idesire it to be distinctly understood that I do not limit myself to thespecific lever F and its actuating-spring Z in a manner shown, as anyspring applied against the end of the arbor Q will suffice to producethe same effectas, for instance, the spring F, (shown in Figs. 7 and 8,)which spring is held byscrewj. Atthe same time that the arbor g is thusmoved outward under excessive speed or power of the spring its collar mis also crowded againstthc spring 11, and a brake action retarding thespeed thereby obtained. Hence a double resistance has been prepared; buteither one may be used in many instances without the other. In fact Ihave noticed that when my device is applied to a music-box it operateswith such extreme nicety that even the action of a greater or lessnumber of studs on the cylinder 0 and its action upon the comb will giverise to an automaticadjustment of speed. \Vhen it is desired topractically neutralize the effect of the yielding of the spring F orlever F upon the arbor g and to partially restrain the action of thebrake m n, I move the lever II so as to push the rod G outward andcompress more tightly the spring Z as far as possible, therebyincreasing the resistance of the lever F. This will cause the fly-arborg to move faster than if it is allowed freer play with the yieldinglever F when the spring Z is relaxed, for when the spring Z iscompressed, as stated, the upper end of the lever F is held with greaterrigidity and the action of the brake on n is partially prevented. Henceby moving the handle r in the slotted plate 3 toward fast, which meanscompressing the spring Z, greater speed is obtained, whereas by movingthe same handle in the opposite direction the speed of the instrument isreduced.

What I claim, and I desire to secure by Letters Patent, is

1. The combination of the longitudinallymovable fiy-arbor g, having aworm thereon, with the worm-wheel 6, arranged for driving it, and with ayielding resistance-piece placed against one end of said arbor,substantially as herein shown and described.
